What Does Business Class from Washington DC to Seoul Cost?
Business class from Washington DC to Seoul is one of the most compelling long-haul routes in the North America to Asia corridor, and CEOFLIGHTS clients regularly secure round-trip fares starting from $2,767 — well below the $6,500+ rates commonly listed on public booking sites. The route connects Dulles International Airport (IAD) in Northern Virginia to Incheon International Airport (ICN), South Korea's primary international gateway, across an average flight time of approximately 14.5 hours.
Two major carriers operate nonstop service on this corridor: United Airlines and Korean Air. United Airlines operates the route as part of its trans-Pacific network out of Dulles, while Korean Air — the flag carrier of South Korea and a SkyTeam alliance member — brings its own premium cabin product to the IAD–ICN pairing. Having two full-service airlines competing on the same route creates genuine pricing competition, which is one reason savvy travelers can find meaningful value here when they know where to look.
